[PATCH] RS485: fix inconsistencies in the meaning of some variables

[Claudio Scordino]

Hi Alan, Hi Greg,

	it seems that the crisv10.c and the atmel_serial.c serial
drivers interpret the fields of the serial_rs485 structure in a different
way.

In particular, it seems that crisv10.c uses SER_RS485_RTS_AFTER_SEND and
SER_RS485_RTS_ON_SEND for the _logic value_ of the RTS pin;
atmel_serial.c, instead, uses these values to know if a _delay_ must be
set before and after sending.

This patch makes the usage of these variables consistent across all
drivers and fixes the Documentation as well.
In particular, SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND will
be used to set the logic value of the RTS pin (as in the crisv10.c
driver); the delay is understood by looking only at the value of
delay_rts_before_send and delay_rts_after_send.

Best regards,

	Claudio

The crisv10.c and the atmel_serial.c serial drivers interpret the fields
of the serial_rs485 structure in a different way.
In particular, crisv10.c uses SER_RS485_RTS_AFTER_SEND and 
SER_RS485_RTS_ON_SEND for the voltage of the RTS pin; atmel_serial.c, instead,
uses these values to know if a delay must be set before and after sending.
This patch makes the usage of these variables consistent across all drivers and
fixes the Documentation as well.
